Give some pieces of Scripture dealing with..___?

[PuellaSumDei]

Temptation, discouragement...and the like?
My mother's really gonna try to quit smoking, and she said she'd like me to provide her with parts of scripture that can keep her going. Of course, there are simpler ways to find parts in Scripture, but I'd really like to see what some of you say, and perhaps provide parts that helped you out as well?

Thank you :]

Here's some...
No temptation has overtaken you that is not common to man. God is faithful, and he will not let you be tempted beyond your ability, but with the temptation he will also provide the way of escape, that you may be able to endure it. - 1 Corintians 10:13

For because he himself has suffered when tempted, he is able to help those who are being tempted. - Hebrews 2:18

Do not be anxious about anything, but in everything, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus. - Philippians 4: 6-8

Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up. - Galatians 6:9
